Energy Efficiency Could Reduce Energy Needs in 2050 by One Third

Posted 16th April 2010.

In 2006 the International Energy Agency announced that through the use of energy efficient buildings, industrial processes and transportation we could reduce the Worlds energy needs in 2050 by one third. Obviously this goes a long way to reducing the effects of global warming. But how are we progressing? What can still be done?

One of the biggest savings to be made is by replacing your old appliances with new energy efficient ones.

Building design can have a big impact, many people dont realise, for example buildings which have south facing windows increase the amount of sun entering the building, which helps provide heat and light, minimising the amount of light & heating usage of the house itself. Also ensuring that the doors and windows are sealed well and the walls and foundations are insulated well can reduce heat loss by 25 to 50 percent. Also the use of underfloor heating, according to underfloor heating specialists Floor Heating Online, can result in a 20% reduction in the amount of energy used to heat a house.

Back in 2006 things were different the above are a given, plus there are the other things that have been around for a long time such as more efficient light bulbs. But now there is more modern ways of helping reduce emissions, Ecotricity, for example, offers electricity produced through entirely green means at almost the same price as the traditional electricity companies. In some cases people have installed their own wind turbine and actually sold electricity back to Ecotricity!
